Hi,

I'm trying to find a nice way to share memory between two unrelated (read no
fork no sproc etc) processes.

I have a Java UI front end that has a C++ layer underneath through JNI which
I want to talk to my C++ Vega/Performer app.

The vgMem functions only help with related processes, so they are out.

I've looked at pfDataPool but that doesn't seem suited to C++ with the only
memory allocation call being:

vol void * pfDataPool::alloc(size_t...)

It seems I have no way of doing a new on my C++ objects for both processes
to share.

Does anybody have any other ways of cleanly sharing memory across unrelated
processes, especially one suited for C++.

Thanks in advance.
